Mfundo yogwirira ntchito yodzipatula - kusiyana pakati pa kusinthana kwapadera ndi chophwanya dera

Kufotokozerakusintha kodzipatula: Solation switch ndi imodzi mwazida zamagetsi zomwe zimagwiritsidwa ntchito kwambiri pazida zosinthira mphamvu kwambiri.Monga momwe dzinalo likusonyezera, ikuyenera kutenga gawo lodzipatula mu dera.Mfundo yake yogwirira ntchito ndi kapangidwe kake ndizosavuta, koma chifukwa cha kufunikira kwakukulu ndi zofunikira zazikulu za kukhazikika kwa ntchito, zimakhudza kwambiri mapangidwe, chilengedwe ndi ntchito yotetezeka ya magawo ndi magetsi.Mbali yaikulu ya chipata cha chida ndi chakuti ilibe mphamvu yozimitsa arc, ndipo imatha kugawidwa ndi kutsekedwa pansi pa malo opanda katundu wamakono.Switch yodzipatula (yomwe imadziwika kuti "switch knife"), nthawi zambiri imatanthawuza kusintha kwapadera kwamagetsi, ndiko kuti, chosinthira chodzipatula chokhala ndi mavoti opitilira 1kV nthawi zambiri chimatchedwa chosinthira chodzipatula, ndipo ndi chimodzi mwazomwe zimagwiritsidwa ntchito kwambiri. zida zamagetsi zomwe zili pazida zosinthira ma high-voltage.Mfundo yake yogwirira ntchito ndi kapangidwe kake ndizosavuta, koma chifukwa cha kufunikira kwakukulu ndi zofunikira zazikulu za kukhazikika kwa ntchito, zimakhudza kwambiri mapangidwe, chilengedwe ndi ntchito yotetezeka ya malo ndi magetsi.Mbali yaikulu ya kusintha kwa kudzipatula ndikuti ilibe mphamvu yozimitsa ya arc, ndipo imatha kupatukana ndi kutseka dera pansi pa malo opanda katundu wamakono.Zosintha zodzipatula zimagwiritsidwa ntchito kusintha ma mayendedwe ozungulira kapena kupatula njira kapena zida kuchokera kumagwero amagetsi.Ilibe mphamvu yosokoneza ndipo imatha kuchotsedwa panjira ndi zida zina musanagwire ntchito.Nthawi zambiri amakhala ndi cholumikizira kuteteza misoperation wa lophimba pansi katundu, ndipo nthawi zina ayenera kugulitsidwa kupewa kutsegula lophimba pansi zochita za maginito vuto lalikulu.Mfundo yogwirira ntchito yosinthira kudzipatula: Nthawi zambiri, ma switch odzipatula amayikidwa kutsogolo ndi kumbuyo kwa wophwanya dera, cholinga chake ndikudzipatula kudera lamagetsi kumagetsi, zomwe zimapangitsa kuti pakhale malo owonekera;popeza kusankha koyambira kwa owononga dera kumatanthawuza chowotcha mafuta, chowotcha mafuta chiyenera kusamalidwa pafupipafupi.Pali nsonga yodziwikiratu yolumikizira, yomwe imathandizira kukonza;kawirikawiri, kabati yotulutsirako imayendetsedwa kuchokera kumtunda wa basi molingana ndi kabati yosinthira, ndipo chowotcha chigawo chiyenera kukhala cholekanitsidwa ndi gwero lamagetsi, koma nthawi zina pangakhale mafoni kuseri kwa wophwanya dera, monga malupu ena, ma capacitors, ndi zina zotero. zida, kotero seti yodzipatula yosinthira imafunikanso kumbuyo kwa wophwanya dera.Chinsinsi cha kusintha kodzipatula ndikuteteza modalirika magawo omwe amayenera kuzimitsidwa ndi zida zopatsa mphamvu zamagetsi apamwamba kwambiri kuti zitsimikizire chitetezo cha ntchito yokonza.Zolumikizana ndi chosinthira chodzipatula zonse zimawululidwa ndi mpweya, ndipo malo olumikizira ndi odziwikiratu.Thekusintha kodzipatulailibe chipangizo chozimitsira arc ndipo sichingagwiritsidwe ntchito kusokoneza katundu wapano kapena wanthawi yochepa.Kupanda kutero, pansi pa mphamvu yamagetsi apamwamba, malo olumikizira adzatulutsa kudzipatula kwamagetsi kodziwikiratu, komwe kumakhala kovuta kuzimitsa paokha, ndipo kumatha kuyambitsa arcing (wachibale kapena interphase short circuit) ndikuwotcha zida, kuyika chitetezo cha moyo pachiswe.Izi ndi zomwe zimatchedwa "load-pull disconnector" ngozi yaikulu.Ma Isolators amathanso kugwiritsidwa ntchito posintha magwiridwe antchito m'mabwalo ena kuti asinthe momwe makina amagwirira ntchito.Kusiyana pakati pa masiwichi odzipatula ndi chophwanyira dera: Zowononga ma circuit Mavuto okwera kwambiri komanso zotchingira ma voltage otsika ndi chipangizo chamagetsi choteteza chomwe chili ndi mtundu wamtundu wozimitsa arc.Dzina lonse la chosinthira mpweya ndi mpweya wamagetsi otsika kwambiri, womwe umagwiritsidwa ntchito makamaka pamabwalo otsika kwambiri.Chifukwa amazimitsa arc potengera gasi ngati chinthu, amatchedwa mpweya wocheperako wamagetsi, kapena chosinthira mpweya mwachidule, ndipo kugawa kwathu mphamvu zomanga kunyumba kumakhala kosinthira mpweya.Isolation switch ndi chida chamagetsi chamagetsi champhamvu kwambiri, chomwe chimagwiritsidwa ntchito kwambiri m'mabwalo okwera kwambiri.Ichi ndi switchgear yopanda zida zozimitsira arc.Chinsinsicho chimagwiritsidwa ntchito kulumikiza dera popanda katundu wamakono ndikulekanitsa magetsi kuti zitsimikizidwe kuti zida zina zamagetsi zimasungidwa bwino.Ikazimitsidwa, imatha kukhala yodalirika molingana ndi katundu wanthawi zonse komanso vuto lanthawi yochepa.Popeza palibe zida zapadera zozimitsira arc, mphamvu yaposachedwa komanso yachifupi siyitha kulumikizidwa.Chifukwa chake, chosinthira chodzipatula chimatha kugwiritsidwa ntchito pokhapokha wowononga dera achotsedwa, ndipo ntchito yonyamula katunduyo ndiyoletsedwa kupewa zida zazikulu ndi ngozi zachitetezo.Only voteji thiransifoma, zomangira ndi zonse katundu thiransifoma amene chisangalalo panopa si upambana 2A, ndipo panopa si upambana 5A, ntchito kudzipatula masiwichi ntchito mwachindunji palibe katundu mizere.Zowononga ma circuit ndi ma switch switch amayenera kugwiritsidwa ntchito ngati mphamvu zambiri, zowononga ma circuit zimatulutsa katundu (zolakwika) zapano, ndi ma switch odula omwe amapanga malo olumikizirana.
